On the Development of Interference-Free Transonic Wind Tunnels,

Abstract

A series of analyses and experiments has been performed to explore the feasibility of a method of wall corrections leading to adaptive walls for interference-free conditions in transonic wind tunnels. A summary of the relevant results is presented. The investigation has indicated that with a modification of a slotted wall by a contouring of the slats a substantial improvement towards interference-free conditions was achieved. The modification, however, was not capable of producing a substantial displacement of the shock toward expected interference-free values. The reasons for this result are discussed and attributed, most likely, to the effect of a pressure at the end of the test section higher than the free stream value.
